4. Creating a characteristic based on the values calculated for Vp.

– Here, the values which have not been adjusted, must be determined by interpolation

between two values.

Note: In this example it is assumed that the inductance does not change

considerably below 3.75 A. For this reason, the same Vp value resulting from the

measurement with a motor current of 3.75 A has been used for all grid points below

3.75 A.

[5-4]

Determined saturation characteristic

5. Set the gain Vp in

C00075

and reset time Tn in

C00076

which were calculated during

the adjustment with the rated motor current (in this example "5 A"):
– Set

C00075

= "10 V/A".

– Set

C00076

= "5 ms".

6. Scale the Vp values on the Y axis of the characteristic to the 100 % Vp setting in

C00075

:
